This is very helpful, thank you. I did not realize there was no "build" step to prepare the EPUB, and that it was only a matter of zipping the files.

There is also the [Plugin] FolderIn and FolderOut - Folder input and output plugins for Sigi if you don't mind using an alternate epub editor.

The ebook I am editing was produced with Calibre, so I will likely continue using it, in case there is author workflow involved. Thank for mention this though, because it seems to have been created for my use-case (git tracked sources). I may look at Sigil in the future.
